Abstract (en)
[Task] It is a task to provide a coating solution that is capable of obtaining a good-quality sol-gel film in terms of not only hardness and transparency, but also external appearance, optical distortion, film thickness, etc., even by an application means capable of application with no equipment, such as hand application. [Solving means] A coating solution for obtaining sol-gel films, the coating solution being that it has a solid matter and a solvent, that the solid matter has a silicon oxide oligomer obtained by subjecting an alkoxysilane to hydrolysis and polycondensation in an acid aqueous solution, that the solvent has an organic solvent having a boiling point of 100°C or higher and a viscosity of 3.5mPa·s or lower and the acid aqueous solution, that number average molecular weight of the silicon oxide oligomer in terms of polystyrene is 500-4000, that the content of the solid matter in the coating solution is 8-30 weight %, and that the content of the silicon oxide oligomer in the solid matter is 10 weight % or greater.
